Abstract
A pulsed laser oscillator includes at least one first electrooptical element that polarizes light according to an applied voltage and a voltage control unit that applies a voltage to the first electrooptical element and controls the voltage. The voltage control unit changes over time a voltage value applied to the first electrooptical element, to control a pulse width of laser light.
